I Get That a Lot (2009)

I Get That A Lot is a reality television special originally created by Danny Harris occasionally airing on CBS, which sets up celebrities in everyday working class jobs. Hidden cameras are used to capture the reactions of unsuspecting customers and bypassers. When the celebrities are recognized, they deny their real identities and say "I get that a lot," until the end of the segment, at which time the cameras are revealed and they come forward about their identities.
The first two episodes also aired internationally in Australia on Channel Ten. There is also a French version based on the format, named Sosie! Or Not Sosie?, produced by Carson Prod and aired on French TV leader TF1.
